RICHARD SIMON, OF NOTTINGHAM, ENGLAND.

DRYING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 655,586, dated August7, 1900.

Application filed February 5, 1900. Serial No. 4,071. (No model.)

To all whom it may concern.- D

Be it known that I, RICHARD SIMON, of Zulla road, Nottingham, England,have invented an Improvement in Drying-Machines; and I do hereby declarethe nature of this invention and in what manner the same is to beperformed to be particularly described and ascertained in and by thefollowing statement with reference to the accompanyin gdrawin gs and theletters marked thereon.

My invention relates to drying-machines; and it consists in theconstruction, combination, and arrangement of parts hereinafterdescribed and claimed.

In the drawings forming part of this specification, Figure 1 is alongitudinal section, partly in elevation, of my improved apparatus withpart of the paddles removed for the sake of clearness. Fig. 2 is asection on the line 3 4 of Fig. 1. Fig. 3 is a view similar to Fig. 1,showing a modified construction. Fig. 4 is a section on the line 1 2 ofFig. 3. Fig. 5 is an end elevation. Fig. 6 is a section on the line 4 5of Fig. 1.

The same letters apply to all the figures.

0 shows semicircular hollow iron troughs formed of cast-iron, arrangedin sections and held together by wrought or cast iron girders or plates,as d, which together constitute the sides of the machine. The troughs care cast hollow, so that steam or other heating medium may circulatetherein, being supplied by pipes, as at e. The condensed or cooled wateris discharged at f and any exhaust-steam or air at g.

a a are drying-cylinders provided with ribs, which increase theheating-surface and also afford bases on which the paddles h are fixed,but plain cylinders may be used. These cylinders contain steam, which isadmitted and discharged by well-known devices through the axles instuffing-boxes on which-the cylinders rest. On these axles are affixedchain wheels 71 and 7;, driven from the shaft j, by means of which thecylinders a a are rotated.

12 is a bundle of tubes fixed in the cast-iron heads 'm 9%, into whichsteam is admitted and exhausted through the axles in the manner abovedescribed.

In Fig. 1 the chain-wheel i is used to rotate the tube bundle b.

it shows paddles, and n shovels fixed onto the drying cylinder orcylinders a and the tube bundle b, respectively. By means of these thesubstance to be dried is divided, agitated, exposed to the heatedsurfaces and air in the troughs and gradually passed from one end of themachine to the other, for which latter purpose some or all are placed ormade at an angle, as shown. The number and angle of these, their shape,and the material of which they are made may be varied to suit thesubstances to be dried.

j is the main shaft of the machine, driven by means of the pulley Z orother suitable arrangement, and by suitably placed chain- Wheels thereongiving motion at the different speeds desirable to the chain-wheelst'and 7c.

0 is an elevator to raise the substance to be dried to the upper portionof the machine, into which it is allowed to fall. By reducing orincreasing the number of buckets on the elevator the quantity fed intothe machine can be regulated.

19 shows scoops attached to the chain-wheel or the discharge end of themachine, which pick up the dried substance from the trough q and throwit into a receptacle suitably placed at the side.

1" is a pair of rollers by means of which lumpy and sticky substancesmay be fed into the machine evenly. They are driven from the shaft j bymeans of chains or other gear ing in the ordinary manner.

3 shows scrapers similar in construction to the paddles h, fixed on theinner side of the troughs c or vertically carried by cross-bars.

The operation of the machine is of a sim= ple character. Steam beingadmitted into the interior of the hollow troughs and into the cylindersor tubes or either of them by suitably-arranged steam pipes and valves,the substance to be dried is filled into the ma chine by either theelevator orthe rolls, where it is divided, agitated, and passed on bythe paddles h and finally emerges driedinto the trough q, whence it isremoved by means of the scoops.

Having now particularly described and as= cert-ained the nature of mysaid invention and in what manner the same is to be performed, I declarethat What I claim is- In drying apparatus, the combination with a casingwhose bottom is made up of holwhich said cylinder is rotated,'and ascoop carried by said gear-Wheel and adapted to move within said trough,as and for the purpose set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

RICHARD SIMON.
